I served these as a party appetizer the other day and they quickly disappeared

6 hard boiled eggs
1/4 cup mayonnaise
1 tablespoon grainy mustard
1/2 can of tuna, drained
Salt, to taste
Ground black pepper, to taste
Paprika, for garnish
Directions
Slice the eggs in half lengthwise and gently pop out the yolks.
Place these into a bowl and mash slightly with a fork.
To the yolks add mayonnaise, grainy mustard, tuna, and salt and pepper. Mix all ingredients together.
Using a spoon or your hands, place a bit of the mixture back into the egg where the yolk once was.
Continue until all eggs have been filled with the mixture. Sprinkle all eggs with paprika for garnish.
